Re : Continous output signal using DAQ usb 6008 in matlab

[Takou]

Good evening,

I am trying to output a continuous signal using the NI DAQ usb 6008. I know that it is not possible to send several samples at once using "putdata/start" because of the DAC. So I send one sample to the output using the function "putsample". When using this code:

ao = analogoutput('nidaq','Dev1');

ch = addchannel(ao,0);

putsample(ao,2)

I am sending one sample (2v) to the output. Can anyone help me to output several samples and then get a continuous signal?

I have tried the function "repeatoutput" but when verifying the output signal using an oscilloscope, I have nothing.

Thank you in advance

Hi Takou,

You have already post with the same topic. Is it the same think, isn't it? 

If yes, Refer to the following link:
